Abstract (en)
[origin: WO2011006861A2] The invention relates to a circuit assembly, comprising at least one transformer having a primary and a secondary winding, wherein the primary winding can be connected by way of a full-bridge circuit having two bridge branches to an input voltage, wherein the full-bridge circuit comprises four switching elements, each having a snubber, and, connected in series to the transformer, a capacitor and a coil, wherein at least one output voltage can be tapped by way of the secondary winding and by way of at least two diodes and an output capacitors, and wherein the output voltage can be controlled by way of a phase shift of the two bridge branches. In order to meet the requirement of low emitted interference, it is proposed to dispose at least one reverse polarization capacitor between the secondary winding and the output capacitor.
